What is the difference between these 3 memories. Ignore that the Flare X is 8GB dimms.
They all have the save frequency and Voltage and Timing. The differences I can see are the TridentZ is using the Intel Z170 Platform Chipset and the G.Skill is using the ADM X370 / B350 Chipset. and the Ripjaws V isn’t doesn’t have a Chipset listed.

I am trying to figure out what to buy.

I am also trying to figure out what Ryzen Motherboard will be able to form just as well with 4 dimms of memory as it does with 2 dimms.
